All methods plywood floor leveling - without the lag on glue , adjustable plywood, with lags

Leveling the floor with the help of plywood is the easiest way to prepare perfectly smooth base for linoleum, laminate or parquet.This method saves a lot of time and effort because it does not require such work, such as the screed device.The advantage of this method lies in the fact that it provides good conditions for a floor ventilation, which is particularly important when nastilke laminate or parquet.

Leveling with plywood can be made after guidance screed or laying sheets of plywood on the joists.For this reason, there are two floor leveling technology using plywood - lags with or without them.

Leveling floor without lag

In this process there are two options: "glue" and "adjustable plywood."Let us consider them in turn.

glue

This option is suitable for those cases where there is practically no height differences, and the screed is completely ready.

Before laying the plywood raskraivajut and laid on the floor in such a way that it will lie.With this installation, you can make a fitting and cutting out specific shapes, taking into account the contours of angles, arches, columns, doorways, etc.Typically, standard plywood sheets to stacking sawn into four equal parts.Sawed sheets and making the necessary excavation, make sure that the ends do not have any bundles or cracks.

Too tight plywood is not necessary to install.In the prepared sheets leave a gap of 5-10 mm, to allow for possible deformation and avoid probable squeak.The gap along the wall should be 10-20 mm.Left clearances allow for good air circulation, than to create optimal conditions for plywood and laid on it parquet or laminate.

order of stacking sheets fixed by marks on the sheets themselves and the floor screed and then all of the plywood is removed.

is followed carefully de-dusted base primed it with a mixture of glue plywood with a solvent or with a bitumen mastic diluted gasoline and wait until completely dry.

Only after this training you can start laying the plywood under the existing scheme.Under the plywood with a view to securing a layer thickness of about two millimeters adhesive or mastic asphalt.

additional sheet after laying on the glue fixed fasteners (screws, anchor bolts, anchors), the length of which must exceed three times the thickness of the plywood.Installation of fasteners made by means of the gun, the distance between the place of installation of fasteners should be more than 20 cm. Hats screws must be recessed.After the laying of the plywood should be sanded using a typewriter or sandpaper.

Adjustable plywood

appeared plywood, eliminating the need for glue with floor leveling in the construction market.Using such a plywood, it is first necessary to drill in accordance with scheme applied to it.With a drilled sheets to the floor, it also drilled hole drill.

The drilled holes are placed anchors with nuts and washers.The height of the nuts put on the laser level, and then placed them on the plywood, which is also fixed on top with the nuts and washers.Extra rods are cut.

This option allows you to align far imperfect floor without lag.The first layer is covered with the second plywood so that the joints were lower in the center area of ​​the plates stacked in the second layer.

alignment with lag

This method is tested by time, but requires strict adherence to the execution procedure.

On cleared of dirt and debris stacked floor waterproofing tape and a thick layer of insulation.They are laid joists bars representing about 2 m and a section 80 × 40 mm.Logs stack with 40-50 mm intervals perpendicular to the direction of light coming into the room.

entire original floor level is checked using to determine its zero point before the start of laying lag.Using screws, every 20 cm put beacons.

Logs stacked, focusing on the screws beacons.In the presence of recesses, under logs installed lining.If you have a bulging of the original floor lag tightly to the insulation layer by means of screws.

installing logs, their Gaugeable in all directions using a spirit level to ensure that the resulting surface is completely flat.After finishing measurements, the entire structure of the lag is fixed on the basis of using the adhesive and anchors.Upon completion of the transaction between the logs transversely stacked bolts that allows you to complete the floor lath.These cells are filled with a layer of thermal insulation material, and hide themselves lags parchment paper or bitumen.

Plywood attached to the base obtained, the sequence of operations resembles that expounded in the description of alignment with glue (prior reupload, the fit and the final blow with fastening).During installation closely followed to ensure that all joints got on a log, and the series of sheets stacked with a certain bias.To impart greater strength floor, the first layer is attached using an adhesive second layer of plywood, which is subjected to grinding.

resulting plywood base has good ventilation, insulation and soundproofing, and provides an ideal surface for laying linoleum, laminate or parquet.
